See BigQueryIO.Read.getTable().

withCoder

public BigQueryIO.TypedRead<T> withCoder(org.apache.beam.sdk.coders.Coder<T> coder)

Sets a Coder for the result of the parse function. This may be required if a coder can not be inferred automatically.

from

See BigQueryIO.Read.from(ValueProvider).

fromQuery

public BigQueryIO.TypedRead<T> fromQuery(java.lang.String query)

See BigQueryIO.Read.fromQuery(String).

fromQuery

public BigQueryIO.TypedRead<T> fromQuery(org.apache.beam.sdk.options.ValueProvider<java.lang.String> query)

See BigQueryIO.Read.fromQuery(ValueProvider).

from

withQueryLocation

public BigQueryIO.TypedRead<T> withQueryLocation(java.lang.String location)

BigQuery geographic location where the query job will be executed. If not specified, Beam tries to determine the location by examining the tables referenced by the query. Location must be specified for queries not executed in US or EU. See BigQuery Jobs: query.

withTemplateCompatibility
